Description

Technical Field

[0001] The utility model relates to the technical field of food processors, in particular to a safe and reliable baby food maker. Background Art

[0002] The baby food maker belongs to one of the food processors, which has functions of food stirring, crushing and even heating and steaming. It is a small household appliance that can quickly crush, stir and steam foods such as fruits, vegetables and meats, and can especially meet the requirements of baby food processing and cooking for infants and the elderly, thus being recognized by more and more consumers.

[0003] The application number is CN202321429451.8, and the invention name is "A Baby Food Maker", which discloses that an exhaust hole is provided on the upper cover. A hollow air duct is provided beside the handle in the positioning groove at the bottom of the upper cover. The upper end of the air duct is connected to the exhaust hole, and the lower end of the air duct is connected to the inside of the cup body through the positioning groove. However, the technical problem existing in this technical solution is that during the steaming process of the baby food maker, the temperature inside the upper cover of the machine head will gradually increase. The driving mechanism is installed inside the upper cover, and the driving mechanism will also generate temperature rise during operation. Due to the combined action of the two temperature rises inside the upper cover, based on the principle of thermal expansion and contraction, the gas pressure inside the upper cover cavity increases significantly, and there is an obvious need for pressure relief. However, the air duct provided inside the upper cover is only used to discharge the steam inside the cup body to the outside of the baby food maker, and the air duct is not connected to the inside of the upper cover, so it is impossible to relieve the pressure inside the upper cover. In the long run, the upper cover is prone to cracking under the action of relatively high pressure, and the components installed inside the upper cover are also prone to damage under the action of high pressure, greatly reducing the service life. In addition, safety problems will also be caused by the explosion of the upper cover.

[0004] The application number is CN201921468216.5, and the invention name is "A Baby Food Maker", which discloses that a pressure relief hole is provided on the outer side of the main body. Steam enters the first exhaust passage from the exhaust port at the lower end of the shaft sleeve, flows through the first exhaust passage to the second exhaust passage and finally discharges from the pressure relief hole, forming a flow path for steam heating. However, the technical problem existing in this technical solution is that in order to prevent the influence of steam on the components installed inside the main body, the entire exhaust passage is only used to discharge the steam inside the heating base to the outside of the baby food maker and is not connected to the inner cavity of the main body. However, during the steaming process of the baby food maker, the temperature inside the main body cavity will gradually increase. The motor is installed inside the main body, and the driving mechanism will also generate temperature rise during operation. Due to the combined action of the two temperature rises inside the main body, the gas pressure inside the main body increases significantly, and there is an obvious need for pressure relief. In the long run, there is no pressure relief channel inside the main body, and the main body is prone to cracking under the action of relatively high pressure repeatedly, and the components installed inside the main body are also prone to damage under the action of high pressure, greatly reducing the service life. In addition, safety problems will also be caused by the explosion of the main body.

[0005] The above-disclosed technical solutions all have the following technical problems: During the steaming process, as the temperature of the main body increases, there is a problem that the pressure cannot be relieved in time due to excessive pressure, resulting in the rupture of the main body housing. The service life of the components inside the main body is greatly reduced, and it is also prone to causing safety accidents. Utility Model Content

[0013] Preferably, an exhaust hole is formed through the housing in the thickness direction, the decorative cover covers outside the exhaust hole, the intake end of the exhaust hole is communicated with the condensation cavity, and the exhaust end of the exhaust hole is communicated with the exhaust gap.

[0014] Preferably, a first clamping rib is formed circumferentially on the side wall of the installation groove, and a second clamping rib that is clamped and matched with the first clamping rib is formed on the inner wall surface of the decorative cover; a positioning hole is also formed longitudinally on the side wall of the installation groove, and a positioning block that is inserted into the positioning hole is formed on the decorative cover, and the positioning block and the second clamping rib are arranged at intervals.

[0015] Preferably, a column is provided in the installation cavity, a through second exhaust passage is provided in the column, an air inlet end of the second exhaust passage is connected to the inside of the body assembly, and an exhaust end of the second exhaust passage is connected to the outside of the shell.

[0016] Preferably, the shell includes an upper shell and a lower shell which are plugged and fixed up and down, the decorative cover is sleeved and fixed on the outer side of the top of the upper shell, the outer edge of the upper end of the lower shell is formed with a first convex edge and a second convex edge from the outside to the inside, a slot is formed between the first convex edge and the second convex edge, and the bottom of the upper shell is plugged and fixed in the slot.

[0017] Preferably, the supplementary food machine further comprises a first sealing member wrapped around the first convex edge, and a side of the first sealing member away from the first convex edge is tightly pressed against the upper shell.

[0018] Preferably, the outer side surface of the second convex edge forms a slot, and the baby food machine further comprises a second sealing member embedded in the slot, and a side of the second sealing member away from the second convex edge is tightly pressed against the inner wall surface of the upper shell.

[0019] Preferably, the supplementary food machine also includes a connecting head installed in the installation cavity and transmission-connected to the output end of the driving mechanism, an oil seal sleeved on the outside of the connecting head, and an elastic member sleeved on the oil seal, and the connecting head is sleeved and fixed on the upper end of the mixing blade.

[0020] The beneficial effects of the utility model are:

[0021] 1. The utility model provides a baby food machine, which has an exhaust gap connected to the installation cavity formed between the decorative cover and the shell. During the cooking process, the temperature inside the upper cover assembly will rise, and the driving mechanism will also cause a temperature rise when working, causing the temperature inside the upper cover assembly to further rise. Therefore, the gas expanded in the installation cavity is discharged to the outside of the baby food machine through the exhaust gap to achieve the purpose of pressure relief, avoid safety problems caused by the explosion of the upper cover assembly, and increase the service life of the driving mechanism. Secondly, the decorative cover is shielded at the gas exhaust outlet of the installation cavity so that the gas will not rush directly to the outside of the baby food machine due to excessive air pressure. The decorative cover has a buffering effect on the gas discharged from the installation cavity, thereby improving the safety of use. In addition, if after a period of use, the sealing of the upper cover assembly deteriorates due to aging of the seals and other reasons, some of the steam generated in the cup body assembly may enter the upper cover assembly through the gap. This part of the steam can be discharged to the outside of the supplementary food machine through the installation cavity and the exhaust gap in turn. Discharging the steam to the outside of the installation cavity in time can effectively avoid the accumulation of steam in the installation cavity, causing problems such as rust on the drive mechanism, while also preventing the growth of bacteria and the generation of odors.

[0022] 2. By forming a condensation chamber on one side of the installation cavity close to the decorative cover, the condensation chamber is connected to the exhaust gap to form a first exhaust channel. The condensation chamber is closest to the exhaust gap, and the temperature of this area is also the lowest compared to the entire baby food machine. When the gas in other areas of the installation cavity runs to the condensation chamber, based on the principle of thermal expansion and contraction, the gas is still in the expansion stage in the condensation chamber, but it expands less than the gas in other areas of the installation cavity, so that the instantaneous amount of gas discharged from the exhaust gap closest to the condensation chamber will not be large, which effectively reduces the impact force generated when the gas is discharged and greatly improves safety. Secondly, a part of the drive mechanism is set in the condensation chamber. The temperature rise caused by the drive mechanism causes the gas in the installation cavity to expand. The expanded gas can be discharged to the outside of the baby food machine through the condensation chamber at the fastest speed, shortening the pressure relief path. In addition, if the sealing performance of the upper cover assembly deteriorates, some of the steam generated in the cup body assembly enters the installation cavity. This part of the steam runs from bottom to top, and the temperature in the condensation cavity can drop suddenly, so that the steam may liquefy when entering the exhaust gap, and then be discharged to the exhaust gap in liquid form. In this case, the exhaust gap plays a role of diversion, which effectively avoids the accumulation of steam in the installation cavity and causes problems such as rusting of the drive mechanism, while also preventing the growth of bacteria and the generation of odors.

[0023] 3. An installation groove is formed circumferentially on the outer side of the top of the shell, and the decorative cover is clamped in the installation groove. A buffer cavity is formed between the inner wall of the decorative cover and the installation groove. The volume of the buffer cavity is larger than that of the exhaust gap. When the amount of gas substance is the same, the larger the volume of the gas is, the smaller the gas pressure is. A buffer cavity is set between the condensation cavity and the exhaust gap, so that the gas transitions from the larger condensation cavity to the smaller buffer cavity, and then is discharged from the extremely small exhaust gap, so that the instantaneous amount of gas discharged from the exhaust gap will not be very large, which effectively reduces the impact force generated when the gas is discharged and greatly improves safety. In addition, the existence of the buffer cavity increases the path of the first exhaust channel as much as possible while ensuring the pressure relief efficiency, so as to extend the gas discharge time and allow the gas to have more time to cool down. When the gas enters the exhaust gap, the expansion pressure can be effectively reduced.

[0024] 4. A first clamping rib is formed on the side wall of the installation groove along the circumferential direction, and a second clamping rib is formed on the inner wall of the decorative cover to engage with the first clamping rib, so as to prevent the decorative cover from being displaced in the axial direction and realize the axial limitation of the decorative cover; secondly, a positioning hole is also formed on the side wall of the installation groove along the longitudinal direction, and a positioning block is formed on the decorative cover and inserted into the positioning hole to prevent the decorative cover from being displaced in the radial direction and realize the radial limitation of the decorative cover. Since the entire food supplement machine will vibrate violently when the driving component drives the mixing blade to work, after the decorative cover is axially and radially limited, the decorative cover can be stably installed in the installation groove even in the working state.

[0025] 5. A first convex edge and a second convex edge are sequentially formed from the outside to the inside along the outer edge at the upper end of the lower housing, and an installation groove for inserting the upper housing is formed between the first convex edge and the second convex edge, so as to realize the fixation of the upper housing and the lower housing; secondly, a first sealing member is arranged between the first convex edge and the upper housing, and is used for sealing the assembly gap at the outer edge when the upper housing and the lower housing are assembled, that is, the first sealing from the outside to the inside between the upper housing and the lower housing is completed; in addition, a second sealing member installed between the second convex edge and the inner wall surface of the upper housing plays a sealing role when steam is about to enter the installation cavity, and the second sealing between the upper housing and the lower housing is completed, thereby forming a double-layer seal between the upper housing and the lower housing, effectively preventing steam and the like from entering the installation cavity and affecting the driving mechanism, and ensuring the normal use of the upper cover assembly.

[0041] The following further elaborates on the present utility model in detail in conjunction with the accompanying drawings and specific embodiments.

[0042] Please refer to Figures 1 - 12 , an embodiment of the present utility model provides a complementary food machine, including a body assembly 1, an upper cover assembly 2, a decorative cover 3, a first seal 2126, a second seal 2127, a connector 4, an oil seal 5, and an elastic member 6.

[0043] The upper cover assembly 2 is disposed above the body assembly 1 and includes a housing 21 having an installation cavity therein, and a driving mechanism 22 for driving the stirring blade 15 is installed in the installation cavity; the decorative cover 3 is sleeved and fixed on the outer side of the housing 21, and an exhaust gap 24 is formed between the decorative cover 3 and the housing 21, and the exhaust gap 24 communicates with the installation cavity.

[0044] It can be understood that an exhaust gap 24 communicating with the installation cavity is formed between the decorative cover 3 and the housing 21. During the cooking process, the temperature inside the upper cover assembly 2 will rise. At the same time, the temperature will also increase when the driving mechanism 22 works, further increasing the temperature inside the upper cover assembly 2. Therefore, the expanded gas in the installation cavity is discharged to the outside of the food processor through the exhaust gap 24 to achieve the purpose of pressure relief, effectively avoiding the rupture of the upper cover assembly 2 due to the long-term action of too high air pressure, and further avoiding the safety problems caused by the explosion of the upper cover assembly 2, greatly improving the service life of the driving mechanism 22 in the installation cavity. Secondly, the decorative cover 3 is covered on the outside of the housing 21, that is, the decorative cover 3 shields the outlet of the gas in the installation cavity from discharging, so that the gas will not directly rush to the outside of the food processor due to too high air pressure. The decorative cover 3 plays a buffering role in the gas discharged from the installation cavity, improving the use safety; at the same time, the decorative cover 3 blocks the outlet of the gas discharged from the installation cavity, improving the aesthetics of the product.

[0045] In addition, after using for a period of time, due to reasons such as the aging of the seal, the sealing performance of the upper cover assembly 2 becomes poor. At this time, some of the steam generated in the cup body 12 assembly may enter the upper cover assembly 2 through the gap. This part of the steam can be discharged to the outside of the food processor through the installation cavity and the exhaust gap 24 in sequence, timely discharging the steam out of the installation cavity, effectively avoiding problems such as the rusting of the driving mechanism 22 caused by the accumulation of steam in the installation cavity, and at the same time preventing the growth of bacteria and the generation of peculiar smells.

[0046] It should be noted that the decorative cover 3 can be in a ring shape or in the form of an arc. The exhaust gap 24 is the gap generated after the housing 21 and the decorative cover 3 are installed and matched, and the size of the exhaust gap meets the amount of instantaneous gas discharged under high pressure; the driving mechanism 22 can include a motor.

[0047] Specifically, a condensation cavity 213 is formed on one side of the installation cavity close to the decorative cover 3. Part of the driving mechanism 22 is arranged in the condensation cavity. The condensation cavity is connected to the exhaust gap 24 to form a first exhaust channel. It can be understood that the condensation cavity is the closest to the exhaust gap 24, and the temperature in this area is also the lowest in the whole food processor. When the gas in other areas of the installation cavity runs to the condensation cavity, based on the principle of thermal expansion and contraction, although the gas is still in the expansion stage in the condensation cavity, it expands less than the gas in other areas of the installation cavity, so that the amount of instantaneous gas discharged from the exhaust gap 24 closest to the condensation cavity is not very large, effectively reducing the impact force generated when the gas is discharged, and greatly improving the safety. For example Figure 2As shown, it is preferable to arrange the condensation chamber at the upper end of the installation chamber. The gas runs from bottom to top, and its temperature gradually decreases during the rising process, further reducing the impact force generated when the gas is discharged, thus greatly improving safety. At the same time, a part of the driving mechanism 22 is arranged in the condensation chamber. The temperature rise brought by the driving mechanism 22 causes the gas in the installation chamber to expand, and the expanded gas can be discharged out of the food supplement machine through the condensation chamber at the fastest speed, shortening the pressure relief path.

[0048] In addition, when part of the steam generated in the cup body 12 assembly enters the installation chamber in the upper cover assembly 2, this part of the steam runs from bottom to top, and its temperature can drop suddenly in the condensation chamber, so that the steam may liquefy when it enters the exhaust gap 24, and then be discharged into the exhaust gap 24 in a liquid form. In this case, the exhaust gap 24 plays a role in guiding the flow, effectively preventing the steam from accumulating in the installation chamber and causing problems such as rusting of the driving mechanism 22, and also preventing the growth of bacteria and the generation of odors.

[0049] In order to sleave the decorative cover 3 on the outside of the housing 21, an installation groove 2111 is formed along the circumference on the outside of the top of the housing 21. The decorative cover 3 is snap-fitted into the installation groove 2111. A buffer chamber 25 is formed between the inner wall surface of the decorative cover 3 and the installation groove 2111. The buffer chamber 25 is respectively connected to the condensation chamber and the exhaust gap 24 to form the first exhaust passage.

[0050] It can be understood that the top of the housing 21 is recessed inward to form the installation groove 2111, the decorative cover 3 is arched outward, and the cross-section of the decorative cover 3 in the vertical direction is arc-shaped. As Figures 2 - 3 shown, an exhaust gap 24 is fixedly connected and formed between the side wall of the installation groove 2111 and the right side surface of the decorative cover 3, and an exhaust gap 24 is fixedly connected and formed between the bottom wall of the installation groove 2111 and the bottom surface of the decorative cover 3. The gas is discharged from the condensation chamber 213 through the buffer chamber 25 to the exhaust gap 24. The volume of the buffer chamber 25 is larger than that of the exhaust gap 24. When the amount of gas substance is the same, the larger the volume for accommodating the gas, the smaller the gas pressure. By arranging the buffer chamber 25 between the condensation chamber 213 and the exhaust gap 24, the gas can transition from the larger-volume condensation chamber 213 to the smaller-volume buffer chamber 25, and then be discharged from the extremely small-volume exhaust gap 24, so that the instantaneous gas volume discharged from the exhaust gap 24 will not be very large, effectively reducing the impact force generated when the gas is discharged, and greatly improving safety; in addition, the existence of the buffer chamber 25 can, while ensuring the pressure relief efficiency, extend the gas discharge time as much as possible, allowing the gas more time to cool down, and the expanded pressure of the gas can be effectively reduced when it enters the exhaust gap 24.

[0051] Among them, as Figures 2 - 6As shown in the figure, in order to discharge the gas in the condensation chamber to the exhaust gap 24, the housing 21 is formed with exhaust holes 2112 penetrating along its thickness direction. The decorative cover 3 covers outside the exhaust holes 2112. The intake end of the exhaust holes 2112 is communicated with the condensation chamber, and the exhaust end of the exhaust holes 2112 is communicated with the exhaust gap 24 through the buffer chamber 25. A plurality of exhaust holes 2112 are provided, and the plurality of exhaust holes 2112 are arranged at intervals along the circumferential direction on the side wall of the installation groove 2111, thereby increasing the exhaust range and further improving the exhaust efficiency. The gas is discharged in sequence through the condensation chamber, the exhaust holes 2112, the buffer chamber 25 and the exhaust gap 24 to form a complete first exhaust passage.

[0052] As Figures 2 - 6 shown in the figure, in order to snap the decorative cover 3 into the installation groove 2111, the side wall of the installation groove 2111 is formed with first clamping ribs 2113 along the circumferential direction, and the inner wall surface of the decorative cover 3 is formed with second clamping ribs 31 that are clamped and matched with the first clamping ribs 2113; the side wall of the installation groove 2111 is further formed with positioning holes 2114 along the longitudinal direction, and the decorative cover 3 is formed with positioning blocks 32 inserted into the positioning holes 2114, and the positioning blocks 32 and the second clamping ribs 31 are arranged at intervals.

[0053] It can be understood that a plurality of first clamping ribs 2113 are provided, the number of the second clamping ribs 31 can correspond to that of the first clamping ribs 2113, and the first clamping ribs 2113 and the second clamping ribs 31 are clamped and matched to prevent the decorative cover 3 from axially displacing and realize the axial limit of the decorative cover 3. A plurality of positioning holes 2114 can be provided, the number of the positioning blocks 32 is equal to that of the positioning holes 2114, the gap between two adjacent first clamping ribs 2113 forms a positioning hole 2114, the positioning holes 2114 are arranged along the longitudinal direction, and the positioning blocks 32 are inserted into the positioning holes 2114 to prevent the decorative cover 3 from radially displacing and realize the radial limit of the decorative cover 3. Since the whole baby food processor will generate intense vibration when the driving assembly drives the stirring blade 15 to work, after the axial limit and radial limit of the decorative cover 3, even in the working state, the decorative cover 3 can be stably installed in the installation groove 2111. When the decorative cover 3 needs to be sleeved onto the upper housing 211, first align the positioning blocks 32 with the positioning holes 2114, and then insert the positioning blocks 32 into the positioning holes 2114 until the plurality of second clamping ribs 31 and the plurality of first clamping ribs 2113 are clamped with each other. At this time, the installation of the decorative cover 3 into the installation groove 2111 can be completed.

[0054] As Figure 7As shown, the machine body assembly 1 may include a machine base 11, a cup body 12, a stirring cup 13 and a bracket 14. The cup body 12 is arranged on the machine base 11. The top of the stirring cup 13 is provided with a flange 131 and the flange 131 is hung on the bracket 14. The bracket 14 is placed at the upper opening of the cup body 12 so that the stirring cup 13 is accommodated in the cup body 12. The gap between the inner wall of the cup body 12 and the outer wall of the stirring cup 13 forms a water storage chamber, and a heating component is arranged at the bottom of the cup body 12. When water is added to the water storage chamber and the heating component is turned on, the steam generated by it can enter the stirring cup 13 to heat the food. The stirring knife 15 is arranged in the stirring cup 13. When the upper cover assembly 2 is covered on the cup body 12, the output end of the driving mechanism 22 can be connected to one end of the stirring knife 15 in a transmission manner, thereby driving the stirring knife 15 to rotate to achieve the mincing of the food in the stirring cup 13.

[0055] like Figures 2 - 4 As shown, in order to discharge the steam in the body assembly 1, a column 2121 is penetrated in the installation cavity, and a through second exhaust channel is opened in the column 2121, the air inlet end of the second exhaust channel is connected to the body assembly 1, and the exhaust end of the second exhaust channel is connected to the outside of the shell 21.

[0056] It is understandable that the second exhaust channel is preferably arranged vertically. When steam exists in the form of gas, based on the characteristics of the gas, the gas is constantly moving upward. Therefore, the second exhaust channel is arranged up and down, and arranged vertically, so that the steam can be discharged to the outside of the baby food machine in the shortest path. Of course, it can also be arranged in an up and down curved manner. The second exhaust channel is the main exhaust channel for steam in the body assembly 1. The steam generated in the body assembly 1 can be discharged to the outside through the second exhaust channel, thereby avoiding the accumulation of steam in the body assembly 1 and causing a sharp increase in internal pressure, thereby ensuring the safety of product use.

[0057] Specifically, Figure 4As shown, the housing 21 includes an upper housing 211 and a lower housing 212 that are inserted and fixed to each other up and down. The upper housing 211 and the lower housing 212 are connected to each other to form the installation cavity. The second exhaust passage is integrally formed with the lower housing 212. The food processor further includes a third seal 23 sleeved outside the cylinder 2121. An annular groove 2123 is formed at the upper end of the cylinder 2121, and the third seal 23 is placed on the annular groove 2123. The third seal 23 can be an O-ring. Thus, when the upper housing 211 and the lower housing 212 are connected to each other, the upper housing 211 abuts against the third seal 23 to form a waterproof seal. Thus, when the steam is discharged to the outside through the second exhaust passage, the steam is condensed into condensate when it meets the cold and is likely to accumulate on the upper housing 211, and part of the condensate will reflow into the body assembly 1 through the exhaust end of the second exhaust passage. Therefore, by providing the third seal 23, it is possible to prevent the condensate from entering the upper cover assembly 2 through the gap when it reflows, thereby ensuring the normal use of the product.

[0058] As Figures 9 - 12 shown, in order to realize the assembly of the upper housing 211 and the lower housing 212, the decorative cover 3 is sleeved and fixed on the outside of the top of the upper housing 211. The outer edge of the upper end of the lower housing 212 is sequentially formed with a first convex edge 2122 and a second convex edge 2124 from outside to inside. A slot hole 2125 is formed between the first convex edge 2122 and the second convex edge 2124, and the bottom of the upper housing 211 is inserted and fixed in the slot hole 2125. It can be understood that both the first convex edge 2122 and the second convex edge 2124 are annularly arranged, the first convex edge 2122 and the second convex edge 2124 are spaced apart, and an inwardly concave slot hole 2125 is formed therebetween. The bottom of the upper housing 211 is inserted and fixed in the slot hole 2125, thereby realizing the fixation of the upper housing 211 and the lower housing 212.

[0059] As Figure 10 、 Figure 12As shown in the figure, in order to achieve the sealing of the upper housing 211 and the lower housing 212, the food supplement machine further includes a first seal 2126 wrapped around the first convex edge 2122, and one side of the first seal 2126 away from the first convex edge 2122 abuts against the upper housing 211. It can be understood that when the upper housing 211 is installed in the slot 2125, there is an assembly gap between the outer edge of the upper housing 211 and the first convex edge 2122. The first seal 2126 is arranged between the first convex edge 2122 and the upper housing 211, and the first convex edge 2122 is arranged outside the second convex edge 2124, which is used to seal the assembly gap of the outer edges when the upper housing 211 and the lower housing 212 are assembled, so that the upper housing 211 and the lower housing 212 form a good waterproof seal, and the steam in the cup body 12 assembly is not easy to enter the assembly gap between the upper housing 211 and the lower housing 212, that is, the first seal from the outside to the inside between the upper housing 211 and the lower housing 212 is completed.

[0060] Furthermore, in order to improve the sealing performance between the upper housing 211 and the lower housing 212, a clamping groove is formed on the outer side surface of the second convex edge 2124. The food supplement machine further includes a second seal 2127 embedded in the clamping groove, and one side of the second seal 2127 away from the second convex edge 2124 abuts against the inner wall surface of the upper housing 211. It can be understood that the second convex edge 2124 is arranged inside the first convex edge 2122, which is used to seal the assembly gap between the upper housing 211 and the lower housing 212 near the installation cavity. If the sealing effect of the first seal 2126 is not good, the second seal 2127 installed between the second convex edge 2124 and the inner wall surface of the upper housing 211 can also play a sealing role when the steam is about to enter the installation cavity, and the second seal between the upper housing 211 and the lower housing 212 is completed.

[0061] It should be noted that both the first seal 2126 and the first seal 2126 can be sealing rings. The installation gap between the first convex edge 2122 and the upper housing 211 is the first to come into contact with the steam. If the first seal 2126 does not have a good sealing effect, the steam will further move inward and enter the installation gap between the second convex edge 2124 and the upper housing 211. Therefore, by arranging the first seal 2126 and the second seal 2127 between the upper housing 211 and the lower housing 212, a double-layer seal can be formed, effectively preventing steam and the like from entering the installation cavity and affecting the driving mechanism 22, and ensuring the normal use of the upper cover assembly 2.

[0062] Such as Figure 11As shown, in order to achieve the sealing of the connecting head 4, the supplementary food machine also includes a connecting head 4 installed in the installation cavity and transmission connected to the output end of the driving mechanism 22, an oil seal 5 sleeved on the outside of the connecting head 4, and an elastic member 6 sleeved on the oil seal 5. The connecting head 4 is sleeved and fixed on the upper end of the mixing blade 15, and the connecting head 4 is transmission connected to the output end of the motor.

[0063] The specific structure of the oil seal 5 is as follows: Figure 11 As shown, the oil seal 5 includes an inner ring 51, an outer ring 52, and a connecting portion 53 respectively connecting the inner ring 51 and the outer ring 52. The inner ring 51 is sleeved on the connector 4, and the elastic member 6 is sleeved on the outer wall of the inner ring 51 to make the inner ring 51 sleeved tightly on the connector 4. Therefore, by sleeved the elastic member 6 on the outer wall of the inner ring 51, the inner ring 51 can be driven to sleeve tightly on the connector 4 under the elastic force of the elastic member 6, thereby preventing the oil seal 5 from deforming during thermal expansion and contraction, which causes it to be unable to fit tightly with the connector 4, thereby ensuring the sealing of the oil seal 5 and the connector 4. It should be noted that the inner ring 51, the outer ring 52, and the connecting portion 53 can all be integrally formed, and the elastic member 6 can be a sealing ring.
